Ah... wrong forum. Also, if Bush isn't running, McCain is the obvious choice. Romney hadn't built up a resume yet. Little does he know he's too unlikable to be president, even though I think his administration went well.
Hypothetically, suppose you are in charge of something. You then hire subordinate A, B, C, D, E, F, and G to new positions. You authorize your powers to them, so that their signatures count as your own until you fire them. The you walk away and are absent 75% of the time. Meanwhile, almost everything except external problems go your way and whatever you were in charge of is a smashing success. Do you deserve credit for fixing and running things smoothly, or does your subordiantes deserve all the credit and you didn't do that.
